water supply valve,
wastewater air release valve
EN1074-4 Full Flow Area Sewage Air release valve Single Body Triple Function Flange Type
. Advanced design with simple mechanism, strong float to prevent cracking during sudden water hammer & quick closure.
. Aerokinetic mechanism to resist blow shut under higher air velocity even up to sonic velocity of air.
. With special fat body design to lower the sewage water flow speed, and let the air out but keep sewage water underneath.
. Keep dirty or corrosive liquid inside the body for safety during operation and no harm to human & surrounding environment
. Internal body guide and upper round wall keep float moving on its rail and keep liquid turbulence flow within this area.
. Much bigger air flow through the nozzle even for higher viscosity liquid.
. Outside screen will be an option for safety and prevent insects or birds in.
. Fully epoxy coated inside and outside for long term services.
. Manufacturing standard meets BS EN 1074-4, AWWA C512. Flange drilling and dimension meets BS EN 1092 and ANSI flange.
Combination kinetic air release valve provide 3 functions:
1.Large air release during fi lling of the pipeline.
During the pipe filling it is responsible of water hammer effects. The SKAR will control the air outflow reducing the water approach velocity and thus minimizing the risk of overpressure.
2.Small air release under pressurized pipeline.
During operation the air produced by the pipeline is accumulated in the upper part. Little by little it is compressed and its volume increases, pushing the liquid level downwards and allowing the air release through the small nozzle.
3.Large air intake during draining of the pipeline.
During pipeline draining, or pipe bursts, it is necessary to bring in as much air as the quantity of outflowing liquid. This is to avoid negative pressure and serious damages to the pipeline and the entire system
